Shock wave is a kind of mechanical pulse pressing strong wave conducted by physical mechanism medium (air or gas). Mp-100 converts the impulse sound wave generated by aerodynamics into accurate ballistic shock wave, which is positioned and moved by the therapeutic probe.
Comparative analysis of clinical efficacy of ESWT combined with core decompression and simple ESWT in the treatment of early avascular necrosis of the femoral head
Methods: 60 patients with avascular necrosis of the femoral head in our hospital were randomly divided into control group and observation group, 30 cases in each group. The control group was treated with ESWT alone, while the experimental group was treated with ESWT combined with core decompression. The Harris system score and therapeutic effect were compared between the two groups before and after operation, There was no significant difference (P > 0.05); Harris score of the control group was lower than that of the experimental group at 6 and 12 months after operation, the difference was significant (P < 0.05); the effective rate of the control group (73.3%) was lower than that of the experimental group (93.3%), the difference was significant (P < 0.05)
